Abstract

In this study, the spatial resolution of the existing 1.5 T magnetic resonance imaging (MRI) was attempted to be improved from 0.7 mm to 50 μm by accurately analyzing the MRI signal using high-precision signal analysis. Non-harmonic analysis (NHA) accurately estimates the Fourier coefficient based on the least mean squares method, and exhibits a higher frequency resolution that is than the fast Fourier transform. A numerical experiment based on measuring parameters of 1.5 T MRI demonstrates the potential use of NHA in visualizing finer structures.
